Demonstrates the ChilkatPath XML Method

Demonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:
Chilkat2 PHP

<?php

use Chilkat2\Xml;

$xml = new Xml();

try {
    $xml->LoadXmlFile('qa_data/xml/pigs.xml');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Get the content of the "species" node for the 1st animal:
$result = $xml->ChilkatPath('animal|species|*');
// Output should be "pot belly pig"
echo $result, "\n";

// Get the content of the "type" node for the 2nd animal:
// Indexing begins at 0.  Therefore, the 2nd direct child having
// the tag "animal" is at index 1
$result = $xml->ChilkatPath('animal[1]|type|*');
// Output should be "House Pig"
echo $result, "\n";

// Find the pig having the name "Nigel" and display the
// birth date.  To do this, we&apos;ll navigate to the node having
// tag="name" with the exact content "Nigel", then navigate up,
// and finally navigate back down to the "birth" node:
$result = $xml->ChilkatPath('/C/name,Nigel|..|birth|*');
// Output should be "June, 1991"
echo $result, "\n";

// Navigate to the 1st animal&apos;s picture and print the filename,
// description, and caption.
// The "$" updates the caller&apos;s internal pointer to reference
// the node that is the result of evaluating the path.
// An empty string is returned for success, and a NULL/nil/0
// pointer (reference) is returned on failure.
try {
    $result = $xml->ChilkatPath('animal|picture|$');
} catch (\Chilkat2\Exception $e) {
    echo "Failed to navigate to animal|picture.\n";
    exit;
}

// Display the contents of the file/description/caption child nodes
echo "Picture Info:\n";
echo $xml->GetChildContent('file'), "\n";
echo $xml->GetChildContent('description'), "\n";
echo $xml->GetChildContent('caption'), "\n";

// Return back to the root of the XML document:
$xml->GetRoot2();

// Display the value of the "spay-neuter" attribute of the 1st animal:
echo "----\n";
$result = $xml->ChilkatPath('animal|gender|(spay-neuter)');
echo $result, "\n";
